Abstract

"ESTAçãO DE ENCURVAMENTO DE PRENSAGEM PARA ENCURVAMENTO DE FOLHAS DE VIDRO, E MOLDE EM UMA ESTAçãO DE ENCURVAMENTO POR PRENSAGEM PARA ENCURVAMENTO DE FOLHAS DE VIDRO". Trata-se de uma estação de encurvamento por prensagem que inclui um molde anular (5) e um molde de face completa (6). Orifícios (10), seletivamente ligados a uma fonte de pressão negativa, são dispostos em partes do molde de face completa (6) que são determinadas pela configuração do molde anular quando o molde anular entra em contato com uma folha de vidro (2) aquecida durante o processo de encurvamento por prensagem. A folha (2) é sugada por pressão negativa através dos orifícios (10) na direção do molde de face completa (6) e adquire assim seu formato. Uma pressão positiva pode ser seletivamente aplicada aos orifícios (10) para desprendimento da folha (2). De acordo com a invenção, pelo menos alguns dos orifícios (10) são dispostos em pelo menos uma ranhura (11) formada na face de moldagem do molde de face completa. As ranhuras (11) de acordo com a invenção aceleram consideravelmente a remoção por pressão negativa do ar entre a face de moldagem do molde de face completa (6) e a folha de vidro (2) destinada a ser encurvada, dessa forma aperfeiçoando o processo de encurvamento por prensagem."PRESS BENDING STATION FOR GLASS BENDING, AND TEMPLATE IN A PRESS BENDING STATION FOR GLASS BENDING". It is a press bending station that includes an annular mold (5) and a full face mold (6). Holes (10), selectively connected to a negative pressure source, are disposed in portions of the full-face mold (6) that are determined by the annular mold configuration when the annular mold contacts a heated glass sheet (2). during the press bending process. The sheet (2) is sucked by negative pressure through the holes (10) towards the full face mold (6) and thus acquires its shape. Positive pressure can be selectively applied to the holes (10) for detaching the sheet (2). According to the invention at least some of the holes (10) are arranged in at least one slot (11) formed in the molding face of the full face mold. The grooves (11) according to the invention considerably accelerate the negative pressure removal of air between the molding face of the full face mold (6) and the glass sheet (2) intended to be curved, thereby improving the process. bending by pressing.
